Electro Co-deposition and Characterization of SiC in Nickel Metal Matrix Composite Coatings on Aluminium 7075

Abstract

In this work, mechanical properties viz., wear resistance, hardness, scratch resistance of electrode deposited Nickel with SiC on Aluminium 7075 are discussed. Electro codeposition of MMC coating has been influenced by many factors viz., current density, voltage, percentage of particle concentration, addition of surfactant and bath composition which are also conferred. Elaborate study has been dispensed on these factors to search out the optimum parameters. The state of art has been discussed for co deposition process of SiC with nickel.
